There's a place in the Zoo where they have these life size statues that look like the are immersed in water. Every time we go the kids climb all over them.
A 'must' stop is the sprinkler park they have there. Especially when its over 90 degrees outside. Sydney opted for the playground across they way where I pushed her on the swings in the hot sun. I'm such a loving mom. Although I did set the timer on my watch for 5 minutes. No more then that.
